Описание к видео Episode 007 - TRS-80 Model 1 System Restoration Part 4: TRS-80 System

Welcome to the eCave. In this fourth episode on the restoration of the TRS-80 Model 1 computer, I finally manage to fix the video corruption and get it functional again. I show you how they modified the composite video to the PAL standard for the European and Australian versions. I also show you how to use the oscilloscope and a logic analyser to work out which of the video SRAM's is giving you incorrect output.
